MATTHEW PERRY 1969-2023: JEN'S FINAL CALL TO MATT 'I TRIED TO SAVE HIM!

Reeling from her worst nightmare come true, the star is wondering, 'What if...?'

Jennifer Aniston broke down in tears during an interview in 2004 over just "the idea of even losing" Matthew Perry while discussing her Friends co-star's addiction demons.

And now the actress is reeling because her biggest fear has been realised.

"All five of the Friends cast are in real bad shape, but Jen's by far taking this the worst," a Hollywood insider tells Woman's Day.

"She's torturing herself with each and every scenario where she could have done this or should have said that. She was one of the last people to speak to him and she'd planned on calling him on Sunday [the day after he died]. She's been going over every word, but no one could have known."

For Jen, says the Hollywood insider, "the real pain is the fact she's been with him almost every step of the way", and the 54-year-old felt she and Matthew had really celebrated a big triumph last year when his book Friends, Lovers And The Big Terrible Thing: A Memoir came out.

"She had huge hopes for a big comeback for Matthew and they were talking about working on a new script together. There was so much to look forward to, but even Jen knows it was his body that gave out, not Matthew," says the source of the actor, who was found unresponsive in his backyard spa by his assistant at his Pacific Palisades home in California on October 28.

Matthew, who endured a life-long battle with addiction, admitted the actress, who he affectionately called "Jenny", "was the one that reached out the most" during his substance abuse struggles. 

"You know, I'm really grateful to her for that," he said last year.
